BLAST-FIIRNACE-STOVE GAS-BURNER.

Specication of Letters Patent may concern:

thatl I, ARTHUR G. MGKEE, a

resident of and State of w Ohio,I have invented a new and usefulImprovement in Blast-Furnace.- Stove Gas-. Burners, of rwhich thefollowingis a specificatiom'the principle of the invention being hereinexplained and the best mode in which I have cont'emplated applying thatprinciple'so` as to` istinguish it from other 1n- Be it known ventions.

in any way This is provided on its upper d" adapted to serve as a:pivotal support for .My invention relates to gas burners for nse inconjunction with blast furnace stoves, and particularly to an improvedmeans for moving burners away -from the doors of stoves of this generalcharacter.

The said invention consists of means here? inafter fully described andparticularly set forth in the claims.

The annexed drawing and the following descri tion set forth in detailcertain means embo ying the invention, the` disclosed means, however,constituting but one of various mechanical forms in which the principleof the invention may be applied. In said annexed drawings; Figure 1-is atop plan of my construction during use, the stove openingbeing shown indotted lines. Fig. 2 is a vertical longitudinal section of the same.Fig.' 3 is a front end view,

artly in section, and more clearlyshowing the operable parts. .Likeletters and numerals of reference refer to similar fparts throughoutlthe several. views.

Leading from the-gas main A is a xed outlet tube which after extending ashort distance ina substantially horizontal direction, leads into andsupports a valve casing C, to which it may be securedY in any approvedmanner.` This casing comprises the usual cap c provided with' an openingc2 for the admission of the valve stem es. nteriorly the valve pro er c*is 'adapted to restv upon or be ralse from the seat c in the followingmanner. Secured tothe cap `desired at c is a standard D. end with apinthe forked lever E. -Thelatter is connected at one end to the valve'stem by means of the connecting links e', while its forked end .andhandle g2,

' nular flanges c" Ato the lower portion L.A Uponr-this shaft,

v.segment j, and in mesh inc loses a nut F, the4 purpose of which willhereinafter more clearlyappear.

A crank shaft) G, having the usual arm g is threaded on its other end,and passes upwardly through a suitable guide bracket H, which is securedby bolh or any other approved means to the an- 08 onthe casing.Continuin in a substantially vertical direction, the shaftG passesthrough an overhanging bearing .d2 of the standard D, -after which itscrews into the nut Fi 4Aswill be readily understood, the stem c3 may byturning this crank be either raised or lowered to respectively open orclose the valve.

Patented Nov. 15, 19,10.' Application led December 11, 1909. VSeria).No. 532,515.

The lowerlnost edge of the casing is -provided with an annular flange c.Resting upon thisiiange so as to be freely rotatable,

is a ringJ providedwith a gear segment y.

Suspended from this segment in any desired manner, as by bolts j', so asto .be rotatable with it, I provide a right angled nozzle K' having. aninterior diameter corresponding of the valve casing' w'ith which itconnects. Suspended upon suitable brackets Z which are secured to thecasingC, is a' second vertically extending crank shaft at a pointopposite the with it, I provide a inion Z2. This shaft'is likewiseprovided with an arm Z3 and handle .l The turningn of the crank rotatesthe pinion, which in turn rotates the Asegment, the latterthen swingingthe nozzle K away from the stove door, to describe the arc'indicated inFig. 1.

The operation of my device is as follows a-Assuming the door of thestove closed'and the `ngzzleff'K-Yof my burner outof position, the doorof the stove will rst be opened, after which'thecrankL is turned, untilthe mouth ,c of the nozzle has swung around to a position directly infrontof the stove opening. The crank G may now be turned to open thevalve, and permitthe gas tio flow'l out through the nozzle,\where itisignited and projected into the stove. After the stove hasbecomesuiiieiently heated, ya reversal of the cranks G and Lrespectively closes the valve, and again swings the mouth, of the'nozzle laround and away from the stove opening, so t at the doorthereafter may bemore easily pproached and closed. Having fullydescribed my invention, what I claim therefore and desire to secure byLetters Patent is 1.' In a device of the character described,

the/combination of a gas main; a valve 'cas- -ing xedly connected withsaid main; andthe combination -of a gas main; a Valve connected withsaid main; means for. opening and closing said valve; a nozzle connectedwith. said valve, and comprising tWo legs having their axes at nieansfor causing said nozzle to sWin about one of said axes.-

3. In a device of the character described, the combination of a gasnected with said main;

means for opening and closing said valve; a nozzle connected Withgsaidvalve, and comprising two legs having thelr axes atan angle; and meanscomprising-a .gear segmentand pinion,

right angles; andl segment; and means" adap'tedto swing said nozzleabouj; one of said axes. g v

4, in a device .of the character described,

Y 'the 'combination of'a gas main; a valve con- 'ncted with said main;'means for opening and .closing said valve; a gear segment rotat-ablymounted upon said valve; a right anone end connected with and fixedlysuspended from said for rot-ating said seggled nozzle having said valve,

ment.
